The cover isprovidedoh its undersidewith thei usual bumper 22 of rubber or other suitable material whereby the same may rest/against the upper side of the seat without marring this waterfsupply when the 'seat is raised into its inoperative position wh ch valve mechanism is preferably" constructed as i'ollows: 1 v f j 18 represents a valve casing wl11ch'isprovid'ed onits opposite si'd'eswithtwo nipples 23,24fwhich are'screwed into threaded'openings in opposite Walls of this casing. These two" nipples have theiraxesarranged 'at angle relatively to'eac'h other and are pro vided at their inner ends with valve seats 25, 26-'eacl1 of which' isnarrangedatright angles to the axis of; the respective nipple, "whereby the seats 'of'both nipples are arranged at an angle to each other; and form-a "V -shaped orwedge sh'aped space between the same. 27 represents a valve gate arrangedin'the valve casing and n i'ovable transversely therein s between the" opposlng inner ends of the valve nipples for the purpose of engaging wit-h or disengaging I from the seats on the inner ends of these nipples and thereby either opening or closing the.

passagethrough the valve casing. Thisgate is of Vssha'ped forminthedirection of its movement so that the'san'ie is capable of en'- gag'i-ng' by a Wedge action with the valve seats at thejinner ends "of both nipples; For

this purpose one-side of the valvegateis arrangedin the same planeas the seat of one of the va-lve nipples while its opposite sideis arranged in the same plane as the v'al've 'fseat Qfthe rot-her} valve nipple. By thus constructing the valve j gate of wedge form and 'arrangingthe seats of the valve nipples also in the-form of a Wedge relaF tively'to each other'it is possible for the-gate "to firmly engage these'seat-s for positively clo-sing the valve and preventing leakage while at -the same'time'this gate is capable of being 'oj'pened freely and withoutundue ;f1"ietio n.-' When any of the cotiperating'surf fa'ces' 'of the valve gate orfthenipple seats screwing in one'or both of these'nipples' suffic'ient to take up this wear, after which the h nipples maybe again held firmly in their adjusted position by'ineansof lock nuts28 ar angedon the external'threads of the nipples beconrawornthesandman be corrected bv andengaging with opposite sides of the valve casing.
